Abstract
The utility model discloses an arrangement structure of a suspension sheave on an elevator counterweight housing. The end part of a sheave shaft, exposed after penetrating out of a shaft hole on a sheave bearing plate, is fixedly provided with a knockout plate; the sheave bearing plate is provided with a fixed plate, and an elastic part for providing an elastic acting force for the knockout plate is arranged between the fixed plate and the knockout plate; the sheave shaft is positioned in the shaft hole through the elastic acting force applied on the knockout plate; the sheave bearing plate is further provided with a safety switch; when bearing balls are broken and result in failure of bearing and further cause jamming or seizing of the bearings, the continuous running of an elevator surely drives the sheave shaft to rotate in the shaft hole, the knockout plate overcomes the elastic acting force of the elastic part to rotate by taking the shaft axis of the sheave shaft as the rotation central line and then contacts with a contact of the safety switch to trigger the safety switch so as to force the elevator to stop running for repair, thereby avoiding the occurrence of accidents of abrasion of steel wire ropes or the sheave shaft, even broken sheave shaft; when the knockout plate stays in a second working state, the knockout plate is separated from the contact of the safety switch through the elastic acting force of the elastic part.
Description
Technical field
The utility model relates to the structure that is provided with of diversion sheave on a kind of Elevator weight sensor frame.
Background technology
On the Elevator weight sensor frame, existing diversion sheave is provided with structure, referring to illustrated in figures 1 and 2, counterweight frame 1 ' comprises the upright beam 2 ' that is provided with about a pair of, the structure that is provided with of diversion sheave comprises the rope sheave loading plates 3 ' that are provided with before and after between the upper end that is arranged on an opposition beam 2 ' two, be opened in two axis holes on the rope sheave loading plate 3 ', the rope sheave assembly 4 ' of two rope sheave loading plate 3 ' upper shaft holes is passed at the both ends of wheel shaft respectively, wheel shaft passes on the periphery of the end of exposing behind the axis hole and offers groove, cooperation by bolts and nuts on the outside face of two rope sheave loading plates 3 ' is fixed with clamp 5 ', clamp 5 ' is stuck in the groove, thereby realizes the location of wheel shaft.By clamp location wheel shaft, forbid that wheel shaft rotates, make wheel shaft change statical stress into by bearing symmetry circulating stress, effectively raise the intensity of wheel shaft.But the bearing on the wheel shaft breaks when making that bearing is stuck in that ball takes place, steel rope severe wear in the grooving of rope sheave in the time of then certainly will causing the elevator operation, even owing to the moment of torsion that applies suddenly can cause the fracture of clamp bolt make wheel shaft in axis hole repeatedly wearing and tearing, finally cause the rope sheave off-axis, under the prerequisite that car safety lost efficacy, cause car to fall.
